“What you are now is the result of what you were. What you will be tomorrow will be the result of what you are now. The consequences of an evil mind will follow you like the cart follows the ox that pulls it. The consequences of a purified mind will follow you like your own shadow. No one can do more for you than your own purified mind—no parent, no relative, no friend, no one. A well-disciplined mind brings happiness.”
Throw a stone into a stream. The running water would smooth the stone’s surface, but the inside remains unchanged. Take that same stone and place it in the intense fires of a forge, and it all melts; the whole stone changes inside and out. Civilization changes a person on the outside. Meditation softens a person from within, through and through.
Meditation sharpens your concentration and your thinking power. Then, piece by piece, your own subconscious motives and mechanics become clear to you. Your intuition sharpens. The precision of your thought increases, and gradually you come to a direct knowledge of things as they really are, without prejudice and without illusion.
Meditation deals with levels of consciousness that lie deeper than conceptual thought. Therefore, some of the experiences of meditation just won’t fit into words. That does not mean, however, that meditation cannot be understood. There are deeper ways to understand things than by the use of words. You understand how to walk. You probably can’t describe the exact order in which your nerve fibers and your muscles contract during that process. But you know how to do it. Meditation needs to be understood that same way—by doing it. It is not something that you can learn in abstract terms, or something to be talked about. It is something to be experienced. Meditation is not a mindless formula that gives automatic and predictable results; you can never really predict exactly what will come up during any particular session. It is an investigation and an experiment, an adventure every time. In fact, this is so true that when you do reach a feeling of predictability and sameness in your practice, you can read that as an indication that you have gotten off track and are headed for stagnation. Learning to look at each second as if it were the first and only second in the universe is essential in vipassana meditation.
The purpose of meditation is to develop awareness.
